The work undertaken was exceptional from start to finish

When choosing Solar Panels for our semi detached home, we gathered multiple quotes. DCR  were the most thorough in guiding us through the available options and designed a system most suited to my needs whilst considering the return on my investment. DCR gave me the most confidence and the work undertaken was exceptional from start to finish. I thoroughly enjoy using my Solar Edge app to see all the data and recommend DCR wholeheartedly to anyone considering Solar for their property.
